My Mom (68 yrs old) is having the same symptoms you are only that it is her left side. They have done all kinds of tests including cat-scan and found nothing. The tests were due to HBP and severe headache. Her blood pressure was 245/140 the day she was admitted and they never found the cause.
Anyway regarding the pressure in her head, she still gets it even when her blood pressure is normal.
We are now looking for a Neurologist. Have you found one and if yes, would you recomend? baseballmomof3, who is your neurologist in Fayette County? I think you would recommend him because you are happy with him/her
